Display Back Enclosure Concave Heat Vents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with a backlight unit face issues of reduced strength due to holes on the rear cabinet, which can lead to cracks, and liquid ingress when spills occur, increasing component count and complexity.
Innovation Solution
A display device design featuring a concave portion on the back surface enclosure with holes for heat release, acting as a handle and liquid barrier, where the holes are strategically positioned above the heat-generating component to enhance strength and prevent liquid ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a plurality of holes is provided on the planar portion of the rear cabinet for heat release, then heat dissipation is improved, but strength of the rear cabinet decreases and cracks may form
Solution Approach 1:
The patent transitions from providing holes on the planar portion (2D surface) to providing holes on the folded portion (3D bent surface). This dimensional change allows heat release functionality to be relocated to a region that does not compromise the structural integrity of the rear cabinet's planar portion, thereby resolving the contradiction between heat dissipation and strength.
2Reliability
If a waterproof cover is disposed inside the enclosure to prevent liquid ingress, then liquid protection is improved, but component count and device complexity increase
Solution Approach 1:
The patent extracts the waterproof cover from the interior of the enclosure and relocates it to the exterior, specifically on the folded portion of the rear cabinet. This extraction eliminates the need for internal waterproofing components while maintaining liquid protection functionality, as the external cover prevents liquid from reaching the holes and entering the enclosure.
Solution Approach 2:
The waterproof cover acts as an intermediary barrier positioned externally on the folded portion, intercepting liquid before it can reach the heat release holes and enter the enclosure. This external intermediary approach provides liquid protection without requiring internal waterproofing components.
